Greek Lexicon of the Roman and Byzantine Periods from B. C. 146 to A. D. 1100 by Older Greek lexicons for the New Testament, e.g., Thayer, Smith, Gingrich, and Souter, while readily available, are not up-to-date enough and/or complete enough to be appropriate for academic work.

The lexicons elsewhere on this page are the tools to use to find the meanings of words. By contrast, analytical lexicons offer only a few glosses for any Greek word. The primary use for an analytical lexicon is to figure out the vocabulary lemma or form from a specific form in the Greek text. Readers are strongly advised to look up the word once it has been found in BDAG, Louw-Nida, Danker's Concise Lexicon, or LSJ..
